WSAEADDRNOTAVAIL (10049)
Cannot assign requested address.
The requested address is not valid in its context. Normally results from an attempt to bind to an address that is not valid for the local machine, or connect/sendto an address or port that is not valid for a remote machine (e.g. port 0).

This means:
When you connect to an address, you cannot connect to port 0. You must select a more "normal" port.
The port depends on what you need it for. The most common ones are 23 (telnet), 21 (FTP) and 80 (HTTP).

Set the RemotePort property of the Winsock control to the wanted port before using the Connect method.
